Your meaning here is unclear. How is it possible to have "a window 
created inside a text widget"?

Try the Toplevel.wm_geometry() function.

Do you want to detect when a window is resized or do you want to resize 
a window programatically.

If the former, bind the Toplevel to '<Configure>'.

E.g.

from Tkinter import *

def config(t):
   def _r(e, t=t):
     geom = e.widget.wm_geometry()
     geom = geom.split('+')[0]
     t.wm_geometry(geom)
     print 'resized %s to %s' % (t, geom)
   return _r

tk = Tk()
tk.title('resize me')
t2 = Toplevel(tk)
t2.title('I get resized')
tk.bind('<Configure>', config(t2))


Is that cool or what?
